The sunshine will be very generous on Monday in Languedoc-Roussillon, the Paca, Rhône-Alpes and Corsica regions throughout the day, according to Météo-France forecasts. Some cumulus will develop on the reliefs of the Alps and the greyness, very present on the south of the Garonne at daybreak, will break up little by little, affecting only the Pyrenean Piedmont in the afternoon.
Over the rest of the country, the clouds will be equal with the clearings until midday, then the sun will take over. In the evening, clouds of altitude will invite themselves from the tip of the Cotentin towards Normandy and the Hauts-de-France.
The minimums will be around 13 to 18 degrees, and 18 to 23 degrees along the Mediterranean coast. Apart from around the Gulf of Lion, Provençal hinterland and lower Rhone Valley where the mercury will peak up to 32 to 36 ° C, everywhere else, the maximum temperatures will drop sharply: the mercury will no longer show than 20 and 23 degrees from Brittany to Hauts-de-France and 25 to 28 degrees in the other regions.
